Models and Simulations
Scientific Motivation and Response Planning
The Modeling group's post-earthquake response will involve producing data products that will aid teams being deployed to the field by providing accurate and current event information. The CME will also use this opportunity to compare theoretical / synthetic data with the actual observed data to fine-tune theoretical models and verify goodness-of-fit.
The CME will strive to collect / produce target data products in response to an event. Following is a list of target data products that will made available through this response site.
- Simple Source parameters (Source USGS, http://earthquake.usgs.gov/earthquakes/eqarchives/sopar/)
- Event parameters (Source USGS)
- Best available source description (Source USGS, http://earthquake.usgs.gov/earthquakes/eqarchives/fm/)
- Best observed shakemap available (Source USGS, http://earthquake.usgs.gov/earthquakes/shakemap/)
- List of observed amplitude data for event (Source CISN / SCEC Data Center)
- EEW performance summary for event (Source SCEC - EEW Testing Center, Maria Luikis, http://scec.org/eew)
- Synthetic ShakeMap from simulation (Source SCEC - EEW Testing Center, Maria Luikis)
- SCEC-VDO images (Source SCEC Response Site - Event Page)
Modeling Group Priorities
- Find extended source description.
- Find updated, verified event parameters.
- Evaulate behavior of Shakerss_feeder for this sequence.
- Find CyberShake rupture similar to event and plot ground motions.
- Define region and simulation scale for wave propagation simulation
- Get ground motion observations for event from Shakerss_feeder for comparison to simulation ground motions.
- Evaluate goodness-of-fit between simulation results and modeling results using SDSU goodness of fit codes.
- Produce a dynamic rupture model for the event.
- Use Cybershake to identify and forecast probability of rupture for faults in the vicinity of the event.
A real-time earthquake display has been setup with data feed from California Integrated Seismic Network at the SCEC main office in USC University Park Campus, ZHS 169. This will be used to display real time earthquake event data and shakemaps. There are plans to add functionality to broadcast this display to the response site - event page at a future date.
SCEC-VDO Images and Animations:
A laptop computer will be available at the SCEC main office in USC UPC, ZHS 169, to produce images and animations from SCEC-VDO in response to an event. This computer will have the latest updated version of SCEC-VDO and is reserved to be used for event response.
